From his post:
All of these artworks fall between 1994-99, while I was at Game Workshop design studio - and were publishing in the army books of that period. I've decided to make them available for purchase (they're taking up to much room honestly) Following a suggestion I've decided to open it up to more people through TGN.
These are just for the original artworks, no publishing or production rights - all rights belong to Games Workshop.
Up first (for here) are all my Chaos (barring epic and Battlefleet Gothic) artworks
